5 / 29 page 5 FN8100.4 May 18, 2006 Notes: (1) The device enters the Active state after any start, and remains active: for 9 clock cycles if the Device Select Bits in the Slave Address Byte are incorrect or until 200nS after a stop ending a read or write operation. (2) The device enters the Program state 200nS after a stop ending a write operation and continues for tWC. (3) The device goes into the Timekeeping state 200nS after any stop, except those that initiate a nonvolatile write cycle; tWC after a stop that initiates a nonvolatile write cycle; or 9 clock cycles after any start that is not followed by the correct Device Select Bits in the Slave Address Byte. (4) For reference only and not tested. (5) VIL = VCC x 0.1, VIH = VCC x 0.9, fSCL = 400kHz (6) VCC = 0V (7) VBACK = 0V (8) VSDA = VSCL=VCC, Others = GND or VCC (9) VSDA =VSCL=VBACK, Others = GND or VBACK (10) VSDA = GND or VCC, VSCL = GND or VCC, VRESET = VCC or GND (11) IOL = 3.0mA at 5.5V, 1.5mA at 2.7V (12) IOH = -1.0mA at 5.5V, -0.4mA at 2.7V (13) Threshold voltages based on the higher of Vcc or Vback. (14) Using recommended crystal and oscillator network applied to X1 and X2 (25°C). (15) Typical values are for TA = 25°C Capacitance TA = 25°C, f = 1.0 MHz, VCC = 5V Notes: (1) This parameter is not 100% tested. (2) The input capacitance between x1 and x2 pins can be varied between 5pF and 19.75pF by using analog trimming registers AC CHARACTERISTICS AC Test Conditions Figure 18.
